BRIEF DESCRIPTION OF THE DRAWINGS

The following drawings form part of the present specification and areincluded to further demonstrate certain aspects of the presentinvention. The invention may be better understood by reference to one ormore of these drawings in combination with the detailed description ofspecific embodiments presented below.

FIG. 1 Arctium lappa (Burdock) root extract, Epilobium angustifolium(Canadian Willowherb) extract, and Cystoseira amentacea/CaespitosaBrachycarpa extract, reduce the expression of proinflamattory cytokinesIL-8, IL-2, and TNF-α in human epidermal keratinocytes.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Acne is commonly referred to as a disorder of the pilosebaceuous unit,which includes the hair follicle, seabaceous gland, and sebaceous duct.Propionibacterium acnes (“P. acnes”), an anaerobic bacteria, is presentin all types of human skin and is part of the skin's natural sebummaintenance system.

Sebaceous glands produce sebum, which is excreted through the sebaceousduct and travels up the follicle. The sebum mixes with common skinbacteria (including P. acnes) and dead skin cells that have been shedfrom the lining of the follicle. While this process is normal, thepresence of extra sebum (note that sebum production can increase whenstimulated by hormones such as androgens) can increase the possibilitythat the pilosebaceuous unit becomes plugged/clogged/obstructed. The endresult of this is oftentimes an inflammatory response, which can lead topimples becoming red, swollen, and painful.

The outward signs of acne on the skin has been categorized asnoninflammatory and inflammatory acne. Noninflammatory acne typicallyincludes the presence of whiteheads and blackheads (respectivelyreferred to as closed and open comedones). These comedones are compactmasses of keratin, sebum, and bacteria, which dilate the follicularduct. A comedone forms when a follicle or sebaceous duct isplugged/clogged/obstructed. Inflammatory acne has been characterized bypapules (pimples), pustules, and nodulocystic lesions which can lead toscarring of the skin.

The compositions of the present invention provide for an effectiveoption for treating, reducing, or preventing acne and its associatedsymptoms (e.g., presence of open and closed comedones, papules,pustules, nodulocystic lesions, skin redness, etc.) by providing topicalskin compositions which include natural botanical extracts such asArctium lappa (Burdock) root extract, Epilobium angustifolium (CanadianWillowherb) extract, Pinus sylvestris bark extract, Ribes nigrum (BlackCurrant) leaf extract, Peumus boldus (Boldo) leaf extract, Spiraeaulmaria (Meadow Sweet) extract, Cystoseira amentacea/CaespitosaBrachycarpa extract, Hydrolyzed soy protein, Navy bean extract, orMushroom extract, or any combination thereof. The compositions of thepresent invention also provide a solution to the above-describedproblems associated with popular anti-acne agents such as salicylicacid, benzoic acid, benzoyl peroxide, and tretinoin. These types ofcaustic anti-acne agents can be incorporated into compositions of thepresent invention at effective amounts while avoiding or substantiallyreducing the unwanted side-effects.

Example 3 Reduced Expression of Pro-Inflammatory Cytokines

Problem:

The increased bacterial lode within acne lesions draws inflammatorycells into the area stimulated by the increased expression ofpro-inflammatory cytokines. As acne lesions emerge, inflammation occursas the skin attempts to heal itself. Overall, redness of the skinsurrounding the acne lesion is intensified by the release ofpro-inflammatory cytokines.

Solution:

In vitro testing was used to examine the effect of plant extractsArctium lappa (Burdock) root extract, Epilobium angustifolium (CanadianWillowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpaextract to reduce the expression of IL-8, IL-2, and TNF-αpro-inflammatory cytokines, which can contribute to a reduction in theintense erythema associated with acne lesions and acne prone skin.

Materials and Methods:

Human adult epidermal keratinocytes were cultured at 37° C. and 5.0% CO₂in standard growth medium. At 70-80% confluent, cells were treated withplant extracts for 5 h in the presence or absence of phorbol myristylacetate. Following, all media was collected and assayed for inflammatorycytokine production analysis using the FaST Quant Kit-MicroSpot ELISAFollowing blocking, supernatant was added to each array. Each arraycontains triplicate spots for each cytokine Arrays were incubated for 3hours and treated with an antibody cocktail, containing one biotinylatedantibody corresponding to each of the arrayed capture antibodies. Arrayswere incubated for 1 h and incubated with a streptavidin-Cy5. Arrayswere imaged on a Perkin-Elmer ScanArray 4000 confocal fluorescentimaging system. Array images were analyzed using Imaging ResearchArrayVision software. Spot intensities were determined by subtractingbackground signal. Spot replicates were averaged and compared to theappropriate controls. Data was calculated as a percent change fromappropriate controls.

Results:

A summary of the results is in FIG. 1. These data demonstrate thatArctium lappa (Burdock) root extract, Epilobium angustifolium (CanadianWillowherb) extract, and Cystoseira amentacea/Caespitosa Brachycarpaextract can act to reduce the expression of known inflammatory cytokinesin human epidermal keratinocytes induced by chemical treatment.Together, these data support the ability of these botanical to reducethe potential for skin irritation associated with acne prone skin.

Example 4 Determining Efficacy of the Compositions of the PresentInvention

The efficacy of compositions or active ingredients within a givencomposition of the present inventions can be determined by methods knownto those of ordinary skill in the art. The following are non-limitingprocedures that can be used in the context of the present invention. Itshould be recognized that other testing procedures can be used,including, for example, objective and subjective procedures. The activeingredients (e.g., Arctium lappa (Burdock) root extract, Epilobiumangustifolium (Canadian Willowherb) extract, Pinus sylvestris barkextract, Ribes nigrum (Black Currant) leaf extract, Peumus boldus(Boldo) leaf extract, Spiraea ulmaria (Meadow Sweet) extract, Cystoseiraamentacea/Caespitosa Brachycarpa extract, or an anti-acne ingredient(e.g., salicylic acid, benzylic acid, benzoyl peroxide, tretinoin, etc.)or any combination thereof, can be tested for their skin efficacy byusing the composition vehicles identified in Tables 1 and 2. As noted inthese Tables, the active ingredients and concentration ranges can vary.

Acne treatment can be visually monitored by applying a treatmentcomposition to acne associated symptoms (e.g., open or closed comedones,papules (pimples), pustules, nodulocystic lesions, etc.) and inspectingthe symptom over a period of time (e.g., 1, 2, 3, 4, 5, 6, days, 1, 2,3, 4, weeks, 1, 2, 3, 4, months, etc.). Similarly, Acne prevention canbe visually monitored by applying a prevention composition to skinsusceptible of exhibiting an acne associated symptom (e.g., chin, cheek,eye, nose, forehead, etc., skin of a child, teenage, young adult, adult,or senior citizen) and inspecting the skin over a period of time.Further, the existence of symptoms associated with acne treatment (e.g.,dry, flaky, or scaly skin or irritated skin) can be visually inspected.

Skin moisture/hydration can be measured by using impedance measurementswith the Nova Dermal Phase Meter. The impedance meter measures changesin skin moisture content. The outer layer of the skin has distinctelectrical properties. When skin is dry it conducts electricity verypoorly. As it becomes more hydrated increasing conductivity results.Consequently, changes in skin impedance (related to conductivity) can beused to assess changes in skin hydration. The unit can be calibratedaccording to instrument instructions for each testing day. A notation oftemperature and relative humidity can also be made. Subjects can beevaluated as follows: prior to measurement they can equilibrate in aroom with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72C). Three separate impedance readings can be taken on each side of theface, recorded, and averaged. The T5 setting can be used on theimpedance meter which averages the impedance values of every fiveseconds application to the face. Changes can be reported withstatistical variance and significance.

Skin clarity and the reduction in freckles and age spots can beevaluated using a Minolta Chromometer. Changes in skin color can beassessed to determine irritation potential due to product treatmentusing the a* values of the Minolta Chroma Meter. The a* value measureschanges in skin color in the red region. This is used to determinewhether a composition is inducing irritation. The measurements can bemade on each side of the face and averaged, as left and right facialvalues. Skin clarity can also be measured using the Minolta Meter. Themeasurement is a combination of the a*, b, and L values of the MinoltaMeter and is related to skin brightness, and correlates well with skinsmoothness and hydration. Skin reading is taken as above. In onenon-limiting aspect, skin clarity can be described as L/C where C ischroma and is defined as (a²+b²)^(1/2).

Skin dryness, surface fine lines, skin smoothness, and skin tone can beevaluated with clinical grading techniques. For example, clinicalgrading of skin dryness can be determined by a five point standardKligman Scale: (0) skin is soft and moist; (1) skin appears normal withno visible dryness; (2) skin feels slightly dry to the touch with novisible flaking; (3) skin feels dry, tough, and has a whitish appearancewith some scaling; and (4) skin feels very dry, rough, and has a whitishappearance with scaling. Evaluations can be made independently by twoclinicians and averaged.

Clinical grading of skin tone can be performed via a ten point analognumerical scale: (10) even skin of uniform, pinkish brown color. Nodark, erythremic, or scaly patches upon examination with a hand heldmagnifying lens. Microtexture of the skin very uniform upon touch; (7)even skin tone observed without magnification. No scaly areas, butslight discolorations either due to pigmentation or erythema. Nodiscolorations more than 1 cm in diameter; (4) both skin discolorationand uneven texture easily noticeable. Slight scaliness. Skin rough tothe touch in some areas; and (1) uneven skin coloration and texture.Numerous areas of scaliness and discoloration, either hypopigmented,erythremic or dark spots. Large areas of uneven color more than 1 cm indiameter. Evaluations were made independently by two clinicians andaveraged.

Clinical grading of skin smoothness can be analyzed via a ten pointanalog numerical scale: (10) smooth, skin is moist and glistening, noresistance upon dragging finger across surface; (7) somewhat smooth,slight resistance; (4) rough, visibly altered, friction upon rubbing;and (1) rough, flaky, uneven surface. Evaluations were madeindependently by two clinicians and averaged.

Skin smoothness and wrinkle reduction can also be assessed visually byusing the methods disclosed in Packman et al. (1978). For example, ateach subject visit, the depth, shallowness and the total number ofsuperficial facial lines (SFLs) of each subject can be carefully scoredand recorded. A numerical score was obtained by multiplying a numberfactor times a depth/width/length factor. Scores are obtained for theeye area and mouth area (left and right sides) and added together as thetotal wrinkle score.

Skin firmness can be measured using a Hargens ballistometer, a devicethat evaluates the elasticity and firmness of the skin by dropping asmall body onto the skin and recording its first two rebound peaks. Theballistometry is a small lightweight probe with a relatively blunt tip(4 square mm-contact area) was used. The probe penetrates slightly intothe skin and results in measurements that are dependent upon theproperties of the outer layers of the skin, including the stratumcorneum and outer epidermis and some of the dermal layers.

Skin softness/suppleness can be evaluated using the Gas BearingElectrodynamometer, an instrument that measures the stress/strainproperties of the skin. The viscoelastic properties of skin correlatewith skin moisturization. Measurements can be obtained on thepredetermined site on the cheek area by attaching the probe to the skinsurface with double-stick tape. A force of approximately 3.5 gm can beapplied parallel to the skin surface and the skin displacement isaccurately measured. Skin suppleness can then be calculated and isexpressed as DSR (Dynamic Spring Rate in gm/mm).

The appearance of lines and wrinkles on the skin can be evaluated usingreplicas, which is the impression of the skin's surface. Silicone rubberlike material can be used. The replica can be analyzed by imageanalysis. Changes in the visibility of lines and wrinkles can beobjectively quantified via the taking of silicon replicas form thesubjects' face and analyzing the replicas image using a computer imageanalysis system. Replicas can be taken from the eye area and the neckarea, and photographed with a digital camera using a low angle incidencelighting. The digital images can be analyzed with an image processingprogram and the are of the replicas covered by wrinkles or fine lineswas determined.

The surface contour of the skin can be measured by using theprofilometer/Stylus method. This includes either shining a light ordragging a stylus across the replica surface. The vertical displacementof the stylus can be fed into a computer via a distance transducer, andafter scanning a fixed length of replica a cross-sectional analysis ofskin profile can be generated as a two-dimensional curve. This scan canbe repeated any number of times along a fix axis to generate a simulated3-D picture of the skin. Ten random sections of the replicas using thestylus technique can be obtained and combined to generate averagevalues. The values of interest include Ra which is the arithmetic meanof all roughness (height) values computed by integrating the profileheight relative to the mean profile height. Rt which is the maximumvertical distance between the highest peak and lowest trough, and Rzwhich is the mean peak amplitude minus the mean peak height. Values aregiven as a calibrated value in mm. Equipment should be standardizedprior to each use by scanning metal standards of know values. Ra Valuecan be computed by the following equation: R_(a)=Standardize roughness;l_(m)=the traverse (scan) length; and y=the absolute value of thelocation of the profile relative to the mean profile height (x-axis).
